SPECIFICATION forming part of Letters Patent No. 363,336, dated May 17, 18187.

Application filed January 24, 1887. Serial No. 925,316.

To all whom it may concern:

Be it knownthat I, ROBERT Eliv HUFF, a citizen of the United States, and a resident of Eureka, in the county of Greenwood and State of Kansas, have invented certain new and useful Improvements in Sirup-Pumps; and I do hereby declare that the following is a full, clear, and exact description of the invention, which will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, which form a part of this specification, and in which- Figure 1l is an axial sectional view of my improved siruppump. Fig. 2 is a side view of the same with the cover of the side removed; and Fig. 3 is a perspective view of the lower end of the suction-pipe, showing portions brokenaway exposing the ball-valve and seat. o

Similar numerals of reference indicate corresponding parts in all the figures.

My invention has relation to that class of sirupspumps in which a circular piston is journalcd cccentrically in aV cylinder and provided with wings or vaues pivoted to the piston and bearing with their free ends against the walls of the cylinder; and it consists in the improved construction and combination of parts of such a pump, as hereinafter more fully described and claimed.

In the accompanying drawings, the numeral 1 indicates a cylindrical casing having an inlet-neck, 2,- and an outlet-neck, 3, diametri@ ally opposite to each other, the inlet or supply pipe 4 fitting upon the inlet-neck, and the discharge-pipe 5 fitting upon the outlet-neck, the necks being screw-threaded. One side of the cylinder is formed by a removablecover, 6, screwed into the side of the cylinder, and the opposite side or head of the cylinder is formed with an eccentric bearing or stuffingbox, 7, in which the short shaft 8 of the cylindrical piston 9 is journaled, the said shaft having a crank, 10, upon its outer end.

The piston is formed with a number of partially-cylindrical recesses, 11, near its periphery, diametrically opposite to each other, and these recesses open through the periphery of the piston through slots 12,

(No model.)

The inner cylindrical ends, 13, of the wings or vanes 14 iit and rock in these recesses, the

vanes projecting through the slots, and the vancs are so curved that they may fit upon the periphery of the piston when folded against it.

The side of the piston facing the removable screw-cover is formed with diametrical grooves 15, extending from one recess to the recess diametrically opposite, and rods or yokes 16 t and slide in these grooves and have studs 17 upon their ends, with which they engage notches or recesses 18 in the ends of the cylindrical inner portions of the vanes, the yokes thus connecting the opposite vanes and taking the place of the springs usually employed in pumps of this class, the vane at one side of the piston, which is forced toward the piston by its'contact with the wall of the cylinder nearest to the piston, forcing through its yoke the opposite vane out, so as to retain its contact with the wall of the cylinder.

The integral side or head of the cylinder is provided with a depression or recess, 22,in its inner side near the outleteneck, slightly past the same, which will serve to allow any sirup which has not passed into the neck to escape into the neck through the said depression, being squeezed out by the vanes being forced iu toward the piston.

The inlet-pipe or su pplypipe is preferably provided with a serrated or notched foot, 19, having a curved valveseat, 20, upon which plays a spherical valve, 21, the concave forni of the upper side of the Valve-seat compelling the valve to cover the aperture in the seat by its gravity.

It will be seen that with slight modifications the pump may be used for other purposes besides for pumping sirup, and that the principle may be employed in rotary steam-engines as well.

Having thus described my invention, I claim and desire to secure by Letters Patent of the United States- In a siruppump, the combination of a cyl inder having diametricallyopposite inlet and outlet apertures, a piston journaled eccentrically in the cylinder and having partially-cyli1r drical recesses near its periphery, and formed with slots iu the periphery opening into the IOC) recesses, wings or vanes having their inner In testimony that I claim the foregoing as cylindrical ends provided with notches and my own I have hereunto affixed my signature 1o pivoted in the recesses, and yokes sliding in in presence of two witnesses.
